Preallocating an array or a vector in matlab before a for loop

9 views (last 30 days)
I have several variables that I want to preallocate in my code before my for loop. I was hoping someone could show me the correct way to write this preaalocation. Currently it looks like this but it is giving me errors
k = 1:24;
sigma_infty = zeros(length(:,k));
eps_infty = zeros(length(:,k));
for k = k
%
sigma_infty(:,k) = [10*k 0 0 0 0 0]';
%
eps_infty(:,k) = S2*sigma_infty(:,k);
end
I keep getting told that I length and/or zeros is an unregognised function and I am unsure how to write the corrct preallocation.
Could someone please clarify how to correctly allocate these variable for me?
Thanks
Alex

N = 24 ;
sigma_infty = zeros(6,N);
eps_infty = zeros(6,N);
for k = 1:N
%
sigma_infty(:,k) = [10*k 0 0 0 0 0]';
%
eps_infty(:,k) = S2*sigma_infty(:,k);
end
